Good question. I was always under the idea that it depends on a combo of your income and what the school itself can offer which you are going to. I hope someone has more information about this than I, I'd really like to know.

For grad school, you're probably going to get a thousand dollars of subsidized loans (at most) and the rest a mix of unsubsidized loans and GradPLUS loans. There is no federal need based aid for graduate schooling.

You are not eligible to receive a Federal Pell Grant because you reported that you have a bachelor's degree (Item 27) or you are working on a degree beyond a bachelor's degree (Item 48). Your Financial Aid Administrator will determine what types of federal student aid you are eligible to receive.
